How long does it take to fully charge the CAT CJ1000DXT jump starter before its first use?

[VonLily]

To ensure optimal performance, the CAT CJ1000DXT jump starter requires a full 40-hour charge before its initial use. This information is detailed in the CAT Professional Jump-Starter Instruction Manual. Use a standard household extension cord (not included) for charging. Always confirm that all ON/OFF switches are in the OFF position during the charging process. The green LED Battery Status Indicator will illuminate steadily when the unit is fully charged. For best results and to maximize the lifespan of your jump starter, fully recharge the unit after each use.
